2nd time nclex take

hello everyone i will be taking my nclex pn for the second time on july 5th, 2018 I'm so nervous because I'm scared of failing again..... but although I'm super scared i feel way more positive this time and have been studying more than i did the first time----way more lol. I have been using Uworld and I'm in love with the rationales even learned new things they never mentioned at school but any who I'm in the 64th% tile and i feel nervous about it i took my assessment test that is included with the subscription and i got a "high" percent of passing the nclex. Does anyone know if that really works ? i want to get a higher percentage but as of now I'm just trying different study methods to remember my labs which i have half of them down as before i knew 0% of them.... any tips for nclex-pn or lab values anyone ? i will greatly appreciate it .
